Title:
GLASS PLATE END FACE MACHINING APPARATUS AND METHOD FOR MANUFACTURING GLASS PLATE
Document Type and Number:
WIPO Patent Application WO/2020/203095
Kind Code:
A1
Abstract:
An end face machining apparatus 1 is provided with: a swingable arm member 4 that supports a grindstone 2; a servomotor 5 that generates a driving force for causing the grindstone 2 to press an end face E of a glass plate G; and a link mechanism 6 that transmits the driving force of the servomotor 5 to the arm member 4. The link mechanism 6 is provided with a first link member 6a that is swingable by the servomotor 5, and a second link member 6b connected in a swingable manner to each of the arm member 4 and the first link member 6a. The end face machining apparatus 1 is configured such that, in a state in which the grindstone 2 is in contact with the end face E of the glass plate G, an angle θ1 which is formed by a direction Ar orthogonal to a longitudinal direction A of the first link member 6a and a longitudinal direction B of the second link member 6b is smaller than an angle θ2 formed by a direction Cr orthogonal to a longitudinal direction C of the arm member 4 and the longitudinal direction B of the second link member 6b.
